Abstract
The utility model discloses a self-cooling cable of a power distribution system in a high-rise building, wherein the cable comprises a metal spiral hose layer, a cable conductor layer, an insulation layer and a protection layer from inside to outside in turn; the insulation layer and the protection layer are in stuck connection; a cylindrical empty cavity passing through the front and rear ends of the cable is formed on the metal spiral hose layer; a plurality of bumps uniformly extend from the inner wall of the empty cavity to the central axis direction of the cable; and the bumps are square or semicircular. The self-cooling cable of the power distribution system in the high-rise building disclosed by the utility model has the benefits that: the cylindrical empty cavity passing through the front and rear ends of the cable is formed on the metal spiral hose layer; therefore, hot air rises along increasing of height; cold air enters from the bottom of the cable; the heat dissipation effect is achieved; because the plurality of bumps uniformly extend from the inner wall of a metal spiral hose to the central axis direction of the cable, the heat contact area is increased; therefore, the heat dissipation effect is further increased.
Description
Technical field
The utility model relates to a kind of cable, relates in particular to a kind of certainly cooling cable of that distribution system of high level.
Background technology
In the prior art, the electric power transfer of distribution system mainly is to adopt common solid power cable in the skyscraper, and it is poor that solid cable exists serious defective one conductor heat dispersion, the larger cable of pair cross-section especially, and heat-sinking capability is especially poor.The way that there is no in the prior art addresses this problem, and can not satisfy people's demand.
The utility model content
The purpose of this utility model is to provide a kind of certainly cooling cable of skyscraper distribution system of perfect heat-dissipating, solves the shortcoming that prior art exists.
The utility model adopts following technical scheme to realize:
A kind of certainly cooling cable of skyscraper distribution system, this cable from-inner-to-outer is followed successively by metal spiral hose layer, cable conductor layer, insulating barrier and overcoat, link to each other by bonding between described insulating barrier and the overcoat, it is characterized in that, described metal spiral hose layer forms the cylindrical cavity of consistent energising cable front and back end, and cavity inner wall evenly extends a plurality of projections to the axis direction of cable.
Further, described projection is shaped as square or semicircle.
The useful technique effect that the utility model possesses is:
The metal spiral hose layer forms the cylindrical cavity of consistent energising cable front and back end, and hot-air rises with the rising of height, and cold air enters from the cable bottom, can play thermolysis; The inwall of metal spiral flexible pipe also evenly extends a plurality of projections to the axis direction of cable, has increased the contact area of heat, has further promoted radiating effect.
Description of drawings
Fig. 1 is that the utility model is from the generalized section of cooling off cable.
Embodiment
By following description to embodiment; to more help public understanding the utility model; but can't the specific embodiment that the applicant is given be considered as the restriction to technical solutions of the utility model, any definition to parts or technical characterictic change and/or to overall structure do form and immaterial conversion all should be considered as the protection range that the technical solution of the utility model limits.
As shown in Figure 1,
Certainly the cooling cable from-inner-to-outer of skyscraper distribution system is followed successively by metal spiral hose layer 1, cable conductor layer 2, insulating barrier and 3 overcoats 4, link to each other by bonding between insulating barrier 3 and the overcoat 4, metal spiral hose layer 1 forms the columniform cavity 5 of consistent energising cable front and back end, cavity 5 inwalls evenly extend a plurality of projections 6 to the axis direction of cable, and the shape of projection 6 can be designed to square or semicircle.Owing to be the distribution system cable of skyscraper, hot-air rises with the rising of height in metal spiral hose layer 1, and cold air enters from the cable bottom, can play thermolysis; A plurality of projections 6 have increased the contact area of heat, have further promoted radiating effect.
Certainly; the utility model can also have other various embodiments; in the situation that does not deviate from the utility model spirit and essence thereof; those of ordinary skill in the art can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection range of the appended claim of the utility model.
Claims (2)
1. the certainly cooling cable of a skyscraper distribution system, this cable from-inner-to-outer is followed successively by metal spiral hose layer, cable conductor layer, insulating barrier and overcoat, link to each other by bonding between described insulating barrier and the overcoat, it is characterized in that, described metal spiral hose layer forms the cylindrical cavity of consistent energising cable front and back end, and cavity inner wall evenly extends a plurality of projections to the axis direction of cable.
2. the certainly cooling cable of skyscraper distribution system according to claim 1 is characterized in that, described projection be shaped as square or semicircle.
